Grinding noise during wash and rinse

First off, I must give thanks to Partselect.com for excellent service. They had the parts I needed, a Diagram of how the parts should go into the Dishwasher, and shipping was very quick and reasonable priced. Thank you Partselect.com.


After dinner we heard our Maytag MDB5100AWW dishwasher start grinding during its wash cycle. Needless to say we found this quite concerning, as this is not what a healthy dishwasher should sound like. After fiddling around with it, I started researching the issue and found Partselect.com where it was stated the “Discharge Housing Assembly (Discharge Pump Housing)” was a common failure point. After disassembling the “Pump and Motor” section of the dishwasher, it was confirmed that the Discharge Housing was indeed broken. Since this Dishwasher is over 8 years old, I figured that I might as well replace a few other parts as well, since I'm in there working on it.


Following the blow-up image of the Pump and Motor picture;

Unscrew part 34

Pull out part 1

Lift Part 2, which is attached to part 36

Unscrew part 5 (6 of them) from part 4, be careful not to loose part 3, sitting inside part 4

Lift out part 6 and 7

Unscrew part 8 and lift out part 9

Unscrew part 27 (three of them) and lift out part 11

The bottom plate of this part is the broken part.


Now, since we are in here replacing a part, we might as well replace a few other parts and give this dishwasher a little longer life. I opted to replace the following parts as well, being that my dishwasher was over 8 years old and the gaskets were showing some age.

Part 4 – Pump Cover and Secondary Filter Assembly; I replaced this part because food often gets caught inside the filters and will throw off the balance during a wash or rinse, thus putting premature wear on bearings and o-rings. My filter had a bunch of food on one side, and the only way to remove the food was to slit open a section of the filter, thus damaging the filter screen.

Part 37 – O-Ring that goes inside the Pump Cover and Secondary Filter Assembly. O-rings are rubber and do wear with age. My dishwasher didn't even have this o-ring; now it does.

Part 3 – Lower Spray Arm Seal; I noticed when pulling these parts out that the hard water in our living area was making these somewhat brittle. When ordering these, get two of them, as the picture indicates. If you order one, the package only contains one, and not two was the image shows it should have.

Part 11 – Discharge Housing Assembly (Discharge Pump Housing). This is the part that is making all the grinding noise. The new part will show that it is built a little differently. It appears that Maytag figured out the weak design of this part and made the replacements stronger.

Part 17 – Even though I ordered this, you don't need to order this part if you order the Part 10 kit. The part 10 kit will include this o-ring. Because its an O-ring, I replaced it; as stated above, o-rings do breakdown.

Part 25 – Pump Gasket; This part should really be called the Pump Housing Gasket, as it isolates the Pump Housing bucket and the Dishwasher tub. I bought this because my original gasket was looking pretty nasty and was coming apart.

Part 10 – Seal Kit (Motor/Pump) (Motor/Pump Impeller and Seal Assembly), this kit includes several components that if purchased separately would easily be twice the cost of this kit. Again, seals and Motor Pump seals are a good thing to replace when needing to do work inside the dishwasher.


Continuing on from the previous dis-assembly list;

Unscrew part 12 and remove part 14, 15 and 16.

Unroll part 17 (o-ring) and remove part 18.

Unscrew parts 19 and carefully remove part 20, being VERY careful to not loose part 39.

Lift out part 22, which will include the bearing inside of part 22.

Pry out part 24 with a pick (the replacement is in the kit of part 10).

To remove part 25, you must Remove part 12 of the Door Assembly (see the Door image) to reach the motor element.

Next unscrew part 14 of the “TUB” i

Poor design causes filters to clog easily

removed lower spray arm and the 6 torx screws that hold the pump cover and secondary filter housing. Removed it and the filter. Removed the pump housing and removed the impeller nut with a 5/16 nutdriver. Removed the old impeller and put in the new one. Replaced the parts in reverse order.

Not enough water pressure to wash soap out of dispenser

Our first effort was to replace the lower washer arm that had splits in the sides of this plastic part. While this increased the water pressure in the wash cycle some it was not enough to adequately wash the dishes. We read that someone else had to clean out the filter which was below the lower washer arm assembly. Thus, we took off the loweer arm assembly by screwing off the hold down assembly in the middle of the arm. We then took off the pump cover by removing the 6 screws that hold it in place with a #3 metric allen wrench. When we took of the cover we could see that the pump filter was so covered with deposits that it was not letting the water through to the pump. Rather than spend hours trying to clean the filter and pump cover we decided it was easier to repalce them. Thus, we ordered the parts and replaced them. The dishwaster is now working fine. We appreciated the information that others had shared that helped us find and fix the problem.

Not getting clean dishes; filter kept getting cloged.

After removing parts, cleaned both upper and lower spray arms, blew out lead to the upper arm, and started to install the new parts.

Unfortunately, the Pump Housing Filter was still cold (freezing weather during shipment and left at the front door) and when I started to bend it into shape it broke in two places. So I tolk the old filter and some Lime away and slowly cleaned it with soft brush to open 95% of the holes.
Once ready it was installed along with the other new parts and the dishwasher works very well.

Simple homeowner repair.

Door leaking, unit was filled with soap film

The repair was very involved, but from previous experience cleaning the dishwasher, it was worth not having to buy a new one. I removed all of the lower parts down to the motor shaft. That process is tricky, but if you do it methodically, and slowly, it is not too bad. The real problem wash the scum that was left behind by the soap used in the dishwasher. After removing all the parts, I ordered the parts I could not clean, and cleaned the parts I could. I figured out that the door was leaking because of the soap scum buildup on all the parts, causing the water level to raise faster than it could be pumped out. After I received the new parts, I simply put everything back together and it works better than ever now. I used the parts layout on your website to help in aiding me to put everything back correctly. I am very appreciative that I can get parts easily through your website, and not have to hire a "service technician" to come out and do the same thing, for the price of a new washer. Thanks!
